- application mea February 1o, 1926.v serial m. 87,230.

This invention relates to new and useful improvements in yarn windings,and partlcula-rly to improvements on the article and method describedand claimed in my Patent No. 1,572,157, and my copendingapplicationSerial No. 62,575, filed October 15, 1925.

In accordance with the method described in said patent a groove ordepression. is formed in the yarn 4 winding byv bearlng with astationary tool afrainst the yarn while it is being wound on the core,the purpose of the depression being to afford a suitable location forknots in the yarn.'

In accordance with the method forming the subject matter of the presentinvention,

the necessity o f providing such special tool is avoided by varying thetension on thel yarn during a predetermined stage of the windingoperation. The tension being increased or decreased when the yarn isbeing wound on a certain section of the core or cone, the yarn lengthswithin that section will be wound tighter and will therefore lie belowthe level of the balance of the yarn within the same layer. Thisincreaseor decrease inv the tensioning may be most expeditiously 4obtained byvarying the position of the standard yarn guide provided on cone windingmachine. Furthermore, the depression may be accentuated or, to a certainextent,` produced solely by bearing with the yarn guide against thatportion of the yarn which it is desired to depress.

While the depression in the yarn may be effected with the usual type ofcone, I have found that a deeper depression'may be obtained if a core of.the type described in my said copendingapplication is used. Instead -offorming a narrow groove or depression in the paper cone or other core, awide groove or depression is formed in this core, preferably". extendingall the way to the apex of the ore. It is easier thus to depress a papercone andfurthermore, a wider depression is obtained which will give theoperator more space within which the knots vmay be placed.

In order more c early to set -forth the nature of the present inventionI shall describe a preferred embodiment thereof. It should beunderstood, however, that yarn windings of the nature described andclaimed in my said patent may be produced by a number of-other -methodsand also that.

the details of the mechanism herein disclosed may be varied within awide range without departing from the spirit of the invention.

In the drawings, Fig. 1 1s a front elevay tion of as much of a conewinding machine as is necessary for a clear understanding of theinvention; y

Fig. 2 is a side elevation of the machine; Figs. 3 to 7 illustratemodifications of the thread guide control, Figs. 3-5 being horizontalcross-sections and Figs. 6 and 7 front and rear views, respectively, ofthe carriage. Fig. 8 is an elevation of a partly woun'd cone; and v Fig.9 is an elevation of a modified form of a partly wound cone.

A paper cone 1 having a corrugated surface is clamped in the usualmanner on the cone holder 2 of a windingmachine. Near its apex thesurface of the cone is narrowed as indicated at 3 (Fig. 8). By means ofalever 4 the cone 1 is clamped in place and rotated through a shaft 5which in turn is driven by the usual driving means including a belt 6. Athread of yarn 7 is fed to the cone from a supply 8 through a suitabletension controlling mechanism 9. The yarn 7 then passes through aV-shaped groove 10 provided in the upper part of a' porcelain button 11and thence is wound directly on the cone 1 The porcelain button 11 iscarried at the upper end of an arm 12 ofresilient material. The arm 12is fastened to a rod 13 which is mounted in the lower part ofa carriage14 in a manner to permit yits travel back and forth in a horizontaldirection. Reciprocatory motion is imparted to rod 13 by means of ashaft 15 carrying a Acam 16l and suitably geared to the driving motor.Since the details of this construction are well known in the art, theirfull description and illustration will be dispensed with. The carriage,v14 is provided with a weighted rotatably mounted on the cam housing 19.The carriage 14`may be rotated around the pivot point constituted by 18and thus moved to and from 'the cone 1. By means of acspring 20, alsomounted on the cam housing and bearing against the weighted end 21 ofthelever 17, the carriage 14 will lbe maintained in any position intowhich it may be moved by hand. However, the

arm 17 having'a hub 18 which is y spring permits the carriage 14gradually to move away from the cone 1n the customary manner as thewinding thereon becomes thicker.

By rotating the carriage towards the cone lithe porcelain button 11 iscarried with it. Since the carriage has a fixed pivot point, therotation towards the cone will result in raising it with lrespect to thecone. The raising of the button with respect to the cone will increasethe tension of the yarn 7 fed through the groove 10. The spring arm 12is so tensioned that it firmly lies against the carriage 14 and thethead is guided in such a manner that it will be wound at apredetermined tension on the cone 1 back and forth over a certain areathereof. As

` best shownv in Fig. 8, during the operation of themachine the button11 being held against a carriage 14, does not quite touch the yarnwinding on the cone 1 and, up to a certain point, remains always in thesame position with respect to the cone. However, when the button 11reaches a point opposite the depressed apex 3 of the cone, it will bemoved towards the cone and therefore slight- -ly raised with respect tothe position it occupies during the balance of its travel. This l' isaccomplished owing to the provision of a steel spring 22 riveted at 23to the carriage 14. The spring is so bent that the spring arms 12carrying the buttonwill glide on top of, this spring and will be held byit away from the carriage and pressed against the cone.

Instead of this arrangement, any number of other arrangements such asthe ones 1lvlustrated in Figs. 3 to 7 may be provided.- In

Fig. 3 the carriage 14 is shown as having a raised cam-like end 23 onwhich the arms 12 may ride. In the arrangement shown in Fig. 4 a bentspring 24 is fastened to the free end of the carriage 14, the end ofthespring lying within a notch 25 provided in the carriage. Invthearrangement shown in Fig. 5, a suitably bent wire26 is mounted on `theend of the carriage. In accordance with the arrangement shown in Fig. 6,instead of mounting a spring like 22 on the carriage 14, a leaf spring30 is fastened with one end to the rear of arm 12. The free end ofspring 30 bears against the carriage 14 and tends to push the guidetowards the cone. However, such forward movement of the guide is limitedby a rod 31 mounted on the carriage 32. The yarn guide reciprocatesbetween'rod 31 and carriage 14, and when it reaches near the apex of thecone where the depression is to be formed, it follows an outwardlybulging pari; `33 of the rod and` thus app-roaches the cone and israised with respect thereto. In the modification illustrated inFig. ,7,that part ofthe carriage 14 which is opposite the depressed apex of thecone is cut away as indicated at'34. A

.wire frame 35 is fastened to the rear of the carriage at 36 to afford afriction surface for the yarn guide. A spring 37 is mounted on thecarriage 14 by means of a bolt 38 which projects through a longitudinalyslot 39 in the spring so as to permit the longitudinal adjustment of thelatter. The forward,- ly bent end`40 of spring 37 projectsin front ofthe opening'i34 and overlaps the end of a spring 41 mounted on the frontof the car.- riage 14 :xt-42. The bulge in spring 40 will control the,forward movement of the guide during its reciprocatory movement. Byvarying the 4adjustment of spring 37, the width of the depression in theyarn winding as well as the pressure on the guide may be controlled tosuit operating conditions.-

Owing to thec fact that while the guide button 11 is travelling back andforth opposite the depressed end 3 of the cone the yarn 7 is wound at agreater tension than during the balance of the reciprocatory movement,that portion of each layer of the yarn which overlies the depressed end3 of the cone will be maintained in alower level than the balance of thelayer. The depression of the yarn winding within this area isaccentuated' by the depression in the lpaper cone and also by thecontact of the button 11 with'the yarn "winding However, as shown inFig. 7, the

required depression may be obtained with a cone having a level surfaceand, of course, other means may be employed for varying the yarntensioning.

It will be obvious to those skilled in the art that the width, depth orposition of the depressed or grooved winding area may be varied, to suitoperating requirements vand 'that the other features of the machine andthe yarn while it is being wound on a certain section of thecore wherebythe yarn winding concentric with said certain section will be depressedwith respect to the balance ofthe winding, and placing knots withinl thedepressed section of the yarn winding'.
